Yes, I would think so too. But rather than reverting it I'd prefer to
understand what's wrong (since I didn't see such problem on any
of my machines here). The stack state suggests that pm_idle is
being left at NULL, and it shouldn't be too difficult to figure out
why this is so. Give me a little time; I'll revert the patch if I can't
figure it reasonably quickly.
